Add guide to codesigning and running on a real device

[kubkon]

It'd be cool if the README included a guide to codesigning and running the generated app on a real device using codesign and xcrun tools (or otherwise).

@jmrico01 would you be willing to add such a short guide to the README?

[jmrico01]

For sure! I'll write something and PR it here when I get the chance. Working on my Zig app at the moment :)

Is there an update on this? I'm interested in using Zig to build an iOS app.

Hey! Sorry I stopped working on my iOS project for a bit, but this is good timing because I've been meaning to revisit. I'll try to add something to the readme in the next day or two - feel free to ping me if I forget.

Aha, seems like @kubkon made some progress while I was away. I had some very rough setup for code signing and hadn't really figured out programmatic deployment to an iOS device, so I am checking out https://github.com/kubkon/zignature and https://github.com/kubkon/zig-deploy, tweaking some outdated things, and seeing if I can make them work.

Yes I did :-) In order to make this example work fully programmatically with zignature and zig-deploy and with any valid and Apple issued developer certificate, there's quite a bit of work left, and in particular:

• zignature needs to learn how to parse XML to learn about bundle's metadata
• zignature needs to learn how to DER encode
• zig-deploy needs more error handling and testing as currently it mainly handles non-incremental installs and doesn't check if app already exists on the target device or not. It also doesn't install any developer profiles on the device.

Anyhow, here's what the entire workflow should look like in the end and what I am aiming for: iOS DX with Zig: demo at Zig Milan meetup.
